Answer:
EH
Step-by-step explanation:
All you have to do is look at the order of the letters/segments and line them up. Like:
ABCD
EFGH
AB AND EF ARE PROPORTIONAL.
A dipeptide bond connects two amino acids. Ser stands for Serine while His stands for Histidine. Isoelectric point is when all charges of the two amino acids cancel out. This can be estimated by finding the average of the isoelectric points (pI) of the two amino acids.
Serine: pI = 5.68
Histidine: pI = 7.59
Average pI = (5.68 + 7.59)/2 =<em> 6.635
</em><em />This is only a rough estimate because an arithmetic average will not coincide with the biochemistry of the amino acids. The true value of the isolectric point is determined through experimentation. However, it would be more ore less around 6.635.<em>

<h3>
Answer: 35.54 degrees</h3>
How I got this answer:
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 5/7
A = arctan(5/7) .... apply the inverse tangent, same as arctangent
A = 35.5376778 ... make sure your calculator is in degree mode
A = 35.54 .... rounding to two decimal places
